15 Causes of Lynch Syndrome

2. Gene Mutation

Our genes carry the DNA information that our body uses to instruct chemical processes in the body. As our body ages, our cells grow and then divide – making copies of DNA. Unfortunately, individuals affected by Lynch syndrome cannot correct changes in the genetic code and repair them.

As genetic mistakes begin to accumulate in organs and tissues within the body, affected cells start to turn cancerous. If left untreated, or undiagnosed, these malignant tumors can spread to other areas of the body through a process known as “metastasis.” Therefore, it’s possible for cancerous tumors to spread from the initial site, such as the bowels, to the liver or kidneys as well.

Doctors who diagnose cancer in people outside of the general risk profile, such as young people who should not be affected by cancer, will typically test for Lynch syndrome to see if it’s a contributing factor to the early development of the disease.
